Ignition Coils: Higher voltage ignition coil (MSD / Accel)
One of the big improvements of the V6 Fiero was the introduction of the computer controlled ignition timing. With this new system
came the 30,000 volt high energy ingition coil. Unfortunately, the factory ignition coil is limited in it's ability to properly provide power
to the engine at certain higher RPMs. While it's arguably one of the more reliable components on the Fiero, it falls short of being able to
provide adequate power to the ignition system above 4,000 rpms. Misfires and a dull spark can lead to fouled plugs and limited
performance. Many aftermarket coils are now available from a variety of manufacturers. Most of these coils all provide a significantly higher
voltage than the stock coil and are able to keep up with an increased rpm range. Users who switch to these coils have found
slightly improved emissions, a smoother idle, and improved performance in the upper rpm range (above 4,000). Here are just a few
of the more commonly offered ignition coils for the Fiero, most of them can be purchased either through the Fiero Store or Summit Racing:

- MSD Blaster High Output Igntiion Coil #51065 - 45,000
- Summit Racing® High Output Ignition Coils SUM-850012 - 40,000
- PerTronix Flame-Thrower HEI and TFI Ignition Coils D3002 - 50,000
- Mallory High Performance Replacement Coils 29210 - 30,000
- Davis Unified Ignition Screamin' Demon Coil 31723 - 45,000
- Moroso ProCoil F Ignition Coils 72358 - 32,093
- Crane PS91 Performance Ignition Coils 730-0491 - 40,000
